The following guide serve as reference lists for Electrical and Mechanical IEC Standards that apply to most Low Voltage Induction Motors. In this context, Low Voltage refers to Motors that operate at voltages less than 1000 V and produce a maximum power of 1000kW. 
IEC 60034 is an International Standard by International Electrotechnical Commission(IEC) for rotating electrical machinery.
A Standard is a specifications document established as a result of consensus between international technical experts working for a standards organization such as the International Electrotechnical Commission (IEC), the European Committee for Electrotechnical Standardization (EN), or a national standards organization (NEMA in the US, DKE in Germany).
Electrical Standards:
- IEC 60034-1 - Rating and performance
- IEC 60034-2-1 - Standard methods for determining losses and efficiency from tests (excluding machines for traction vehicles)
- IEC 60034-2-2 - Specific methods for determining separate losses of large machines from tests – Supplement to IEC 60034-2-1
- IEC 60034-8 - Terminal markings and direction of rotation
- IEC 60034-11 - Thermal protection
- IEC 60034-12 - Starting performance of single-speed three-phase cage induction motors
- IEC 60034-17 - Cage induction motors when fed from converters – Application guide
- IEC 60034-25 - Guidance for the design and performance of AC motors specifically designed for converter supply
- IEC 60034-26 - Effects of unbalanced voltages on the performance of three-phase cage induction motors
- IEC 60034-30 - Efficiency classes of single-speed three-phase cage induction motors(IE-Code)
- IEC 60034-31 - Selection of energy-efficient motors including variable speed applications – Application guide

Mechanical Standards:
- IEC 60034-5 - Degrees of Protection provided by the integral design of rotating electrical machine (IP code)
- IEC 60034-6 - Methods of cooling (IC code)
- IEC 60034-7 - Classification of types of construction, mounting arrangements and terminal box position (IM Code)
- IEC 60034-9 - Noise limits
